How to convert WEBM to PPT?

First, users need to upload the WEBM file they want to convert to your website. Your interface should have a prominent 'Choose File' button. When you click this button, a window will pop up where you can select and upload the WEBM document from your computer, phone, or tablet.

After uploading the file, users need to specify the format they want to convert it to. On your website, there should be a drop-down menu or a clear list of all available target formats. Users can simply find and select the PPT format from the list.

After confirming that the file and target format are correct, users click a 'Convert' button. The conversion process will proceed in the background. Once completed, your website will provide a download link or button for users to click to download the converted PPT. The file is saved to their device.
